DETAILED DESCRIPTION

[0060] In connection with the description of the following figures, the reference indicators, in the event that they are not explicitly explained in individual figures, refer to the additional figures.

[0061] In FIGS. 1A, 1B, 1C, a bushing 20 is shown which is set up to be mounted so as to be rotatable on a spindle (not shown). The bushing has a coupling part 21 and a mounting segment 25, wherein the coupling part 21 is essentially formed by two annular segments 22, 22a, 22b. A support arm (not shown) may be fastened to the mounting segment 25.

[0062] Shown in FIG. 1A is the bushing 20 from the side of the mounting segment 25, wherein a face 25a is visible. The face 25a has a face surface 25a.1 that is flat, at least in sections. A support arm may be placed on the face surface 25a.1, and normal forces may be transmittedin particular, to ensure [sic] a non-positive fit via static friction. Formed on the face 25a is a positive-fitting safety segment 25.2 to counter vertical movement and/or twisting and a positive-fitting safety segment 25.3 to counter axial movement and/or twisting. An eyelet bolt 25.4 is also indicated for screwing down a casing.

[0063] The safety device 25.2 is preferably a cutout or a recess or depression and has an upper and a lower surface. A pin 13.1c of the support arm 13 (see FIG. 3A) may be held in position between these two surfaces. One or more safety segments/cutouts 25.2 may jointly receive large torsion moments and secure the support arm against twistingin particular, with large dynamic impulses or moments when the support arm strikes in a jerky manner on an upper or lower stop. A gap between the safety segments 25.2 and the support arm is preferably smallapproximately 0.1 mm.

[0064] The safety segments 25.3 preferably do not rest so closely on the support arm. They also thereby transfer barely any torsion moments, or none at all. The safety segments 25.3 are set up to position the boom horizontallyin particular, in order to be able to assemble fastening elements/bolts in a simple way.

[0065] The mounting segment 25 has a safety device 25.1 for the support arm, at/on which the support arm may be supported. The safety device 25.1 is preferably designed as a longitudinal profile segment that projects radially from the bushing 20. The safety device 25.1 has a support segment, a support surface, and/or a support contour 25.1a on which a corresponding segment of the support arm can be borne. To mount the support arm 13 at the bushing 20, the safety device 25.1 can thus be inserted into an axially extending interior 13.6 of the support arm 13 (see FIGS. 1A, 3A, and 5). The support contour 25.1a thereby comes to be placed on a corresponding bearing surface 13.4c at the bearing segment 13.4b of the support arm 13 (see FIGS. 3A and 3B).

[0066] The upper annular segment 22a of the coupling part 21 has a face surface 22.1 at which an additional component (for example, an additional bushing) may be arranged. Each annular segment has an inwardly facing shell surface (bearing seat) 22.2 on which the bushing 22 can be mounted around the spindle.

[0067] The lower annular segment 22b of the coupling part 21 has multiple reliefs 22.3 for locking a slip ring, as well as multiple reliefs 22.4in particular, through-holesfor locking a cover cap. One or more threaded holes 22.5 for braking screws are also provided.

[0068] A receptacle 23 for a locking bolt for setting a stop position or rotation position is also provided on the underside of the bushing 20.

[0069] In FIG. 1B, the bushing 20 is shown from an inner side, from which fastening means (not shown) can be mounted. The mounting segment 25 has four lead-throughs 25.5 for fastening meansin particular, for bolts. A placement surface 25.5a for fastening means is formed at each lead-through 25.5. The mounting segment 25 also has a recess 25.7 for conduits or cables, which is arranged between two lead-throughs 25.5 for fastening means. The support arm 13 is thus to be affixed on the bushing 20 (see FIG. 5) via at least one (preferably four) fastening means 40 that flank the safety device 25.1 at one or more corners (in particular, four corners), so that a connection between the support arm 13 and the bushing 20 is achieved that is both rotationally fixed and tight in the axial direction (thus, along the longitudinal axis L) of the support arm 13 or, respectively, in the radial direction of the bushing 20.

[0070] In FIG. 1C, it is apparent that the safety device 25.1 forms the lower segment of the recess 25.7. Provided on an underside of the upper annular segment 22a are threaded holes 22.6 for the fastening of cable guidance means.

[0071] The design of the bushing 20 is shown in additional views in FIGS. 2A, 2B, 2C.

[0072] In FIG. 2A, the bushing 20 is shown in an alignment in which the radial direction r corresponds to the horizontal direction. In this alignment, the bushing 20 is preferably mounted so that the bushing 20 may rotate around a vertically aligned rotation axis. The rotation axis D defined by the annular segments 22a, 22b is aligned exactly in the vertical direction z. The face 25a extends in a plane orthogonal to the radial direction r. The safety device 25.1 extends in the radial direction r.

[0073] In FIG. 2B it is apparent that the recess 25.7 is formed only in the mounting segment 25, but not in the annular segment 22. Cables or conduits may be guided from the support arm (not shown) through the recess 25.7 between the upper annular segment 22a and the lower annular segment in the direction of the rotation axis D.

[0074] In FIG. 2C, it is apparent that the support segment, the support surface, or the support contour 25.1a of the safety device 25.1 are formed by a self-contained surface which is as large as possible with regard to the width of the support arm 13 indicated by the dashed line. The width of the support segment 25.1a is, in particular, at least half, and preferably at least , of the width of the support arm. Greater loads may in this way be transferred without stress peaks, or without the risk of deformation of the profile of the support arm. One or more recesses 22.7 for conduits or cables are provided on an underside of the lower annular segment 22b. In other words, cables may optionally be directed between the annular segments at the spindle (not shown), or downward or upward out of the bushing 20. The cable guidance is an aspect which must be considered with support systems of modular design, since, in most instances, the medical technology devices held by the support system require a plurality of electrical or other supply lines. The bushing 20 enables different arrangement variants for these conduits, and thereby remains mountable in a simple manner.

[0075] Shown in FIGS. 3A, 3B, 3C is the cross-section profile Q of a support arm 13 extending along a longitudinal axis L. In a state in which it is mounted on the previously described bushing 20, the longitudinal axis L is aligned in the radial direction r. The support arm 13 is formed by a circumferential wall 13a which satisfies at least three functionsin particular, a fastening, a securing, and/or a centering, as well as an arrangement of cables.

[0076] In FIG. 3A, a first mounting interface 13.1 is shown, wherein the mounting interface 13.1 is formed essentially by a face or face surface 13.1a of the support arm 13. Formed at the mounting interface 13.1 are four receptacles 13.1bin particular, in the form of screw channels for fastening means. The receptacles 13.1b are thereby formed in the wall 13a.

[0077] Formed at the mounting interface 13.1 are pins 13.1c for rotation locking and vertical positioning, as well as cutouts 13.1d for horizontal positioning.

[0078] The wall 13a has four corners or folds 13a.1 in which the receptacles 13.1b are arranged.

[0079] The wall 13a also forms a channel 13.4in particular, a cable channel open at the top. Two grooves 13.4a for locking cable securing means are formed in an upper segment of the channel 13.4.

[0080] The wall 13a has a bearing segment 13.4b which is set up to be borne at/on the geometrically corresponding safety device 25.1.

[0081] Visible in FIG. 3B is a bearing surface 13.4c formed on the bearing segment 13.4b, on which bearing surface 13.4c can be borne the support arm 13 on the safety device 25.1. The bearing surface 13.4c and the support surface 25.1a of the safety device 25.1 preferably have at least approximately the same curvature radius. FIG. 3B shows that the bearing segment 13.4b forms a U-profile. A large weight may in this way be accommodated. The U-profile can ensure a large carrying force and high dimensional stability. Thanks to the U-profile, the safety device 25.1 may be formed to be comparatively short in the radial direction. A groove 13.2 for fastening casing parts is provided on an outside of the wall 13a.

[0082] A second mounting interface 13.5 of the support arm 13 is shown in FIG. 3C. The mounting interfaces 13.1, 13.5 are respectively provided at a free end of the support arm 13specifically, at the respective faces 13.1a, 13.5a. The mounting interface 13.5 comprises four receptacles 13.5b for fastening meansin particular, in the form of screw channels. The receptacles at both mounting interfaces are preferably of identical design. Also provided on the face 13.5a are pin holes 13.5c extending in the radial direction r or, respectively, in the longitudinal direction L, for rotation locking and for vertical positioning. Pins for alignment and securing of an additional bushing (cf. FIGS. 4A, 4B) may be introduced into these pin holes 13.5c.

[0083] The support arm 13 is shown in its entirety in FIG. 3D. The mounting interfaces 13.1, 13.5 are respectively provided at a free end of the support arm 13. It is apparent that the support arm 13 is shaped in the form of an extruded profile extending in a straight line along the longitudinal axis L.

[0084] Shown in FIGS. 4A, 4B is an additional bushing 30 which defines an additional rotation axis D1. The additional bushing 30 is preferably mounted on a forward end of the support arm that faces toward a medical technology device. Like the first (rear) bushing 20, the additional bushing 30 has a coupling part 31 with annular segment 32, as well as a mounting segment 35. The mounting segment 35 has a face 35a having one or more face surfaces 35a.1, as well as four lead-throughs 35.5 for fastening means, wherein the lead-throughs respectively have a placement surface 35.5a for placement of the fastening meansfor example, for placement of a screw head. The mounting segment 35 also has a positive-fitting safety segment 35.2 to counter vertical movement and/or twistinghere, in the form of two pin holes.

[0085] Via holes 35.6 that are flush with two of the lead-throughs are introduced at the coupling part 31. The via holes 35.6 facilitate the assembly radially from the outside. A recess 35.7 for conduits or cables is provided between two of the via holes 35.6, viz., the upper via holes 35.6.

[0086] Shown in FIG. 5 is a boom 11 that can be mounted so as to rotate, comprising the rear bushing 20 and the forward bushing 30, as well as the support arm 13. Also indicated are fastening means 40 in the form of bolts.

[0087] Shown in FIG. 6 is a stand apparatus 1 installed on a ceiling, which stand apparatus 1 comprises three booms 11 that respectively comprise a rear bushing 20, a support arm 13, and a forward bushing 30. Two of the support arms 13 are mounted so as to be rotatable on a spindle 3. The stand apparatus 1 positions and holds two medical technology devices 2 which are mounted in pivot joints 12 at the respective support arm 13 or the respective forward bushing 30.
